Juice quality, adventitious roots, growth rate and senesced leaves, green leaves were examined under flood stress conditions for six sugarcane genotypes I 112-01, I 6-04, I 39-04, I 152-04, I 189-04 and Isd 38. The pot study was conducted in an artificially created flood in a concrete water tank in the Bangladesh Sugarcane Research Institute during the 2010-2011 cropping seasons to screen flood tolerant clones. The clones I 6-04 and Isd 38 exhibited high tolerance to flooding following 30, 60 and 90 days and 30 cm depth above pot soil sustained floods. These varieties had >45% green leaf after 120 days stress periods. Clones I 112-01, I 39-04 and I 189-04 showed tolerant reactions following 30, 60 and 90d flood stress periods with > 40% green leaf after 90d. Clone I 6-04 produced the highest adventitious root (AR) (145.0 g/plant) followed by Isd 38 (110.0b g/plant).The clones I 6-04 and Isd 38 showed highest growth rate. Isd 38 showed highest Brix percent (20.15) and pol percent (14.52) followed by I 6-04 (Brix 19.95 and pol 14.12). Our results indicate that clone I 6-04 and Isd 38 performed better under flood stress conditions than other clones for selecting a stress tolerant variety
